How to Prevent Grease Trap Overflows
Most grease trap overflows are preventable. The businesses that rarely deal with emergencies treat maintenance as non-negotiable and follow a few simple kitchen practices consistently.

Stick to your scheduled maintenance
Your local water authority sets a required cleaning frequency for a reason. Skipping or delaying services allows grease to build up beyond safe levels. Once a trap reaches capacity it will overflow — and emergency pump-outs cost significantly more than scheduled services, before factoring in lost trading time.
Keep fats, oils and grease out of drains
Train kitchen staff to scrape plates and cookware into the bin before washing. Collect used cooking oils in a container for recycling rather than pouring them down the sink. This single habit has the biggest impact on how quickly your trap fills.
Use drain strainers
Fit strainers on all kitchen sinks to catch food solids before they enter the trap. They are inexpensive and make a measurable difference to the rate of buildup.
Monitor your trap
Keep records of your pump-out dates. If your trap is consistently hitting capacity earlier than expected, discuss a tighter schedule or a larger trap size with your service provider.
Never use chemical drain cleaners
Chemical products don't address the underlying cause and can damage trap components. If you're experiencing slow drains or odours, contact your service provider rather than attempting a DIY fix.
